Superplastic working of hybrid metal matrix composites reinforced with SiC particles

摘要

Hybrid metal matrix composites, which made of SiCp/Al metal matrix composites and monolithic superplastic aluminum alloy and fabricated by hot pressing, can be very useful in practical usage where more lightening or partial machining is required.Cylindrically hybridized rods and layer-hybridized blanks were used to investigate the workability of the hybrid metal matrix composites under compressive and tensile stress. The results revealed that precise and partially strong machine parts can besatisfactorily produced by this process.
